I received a similar notification about one of our prefixes also a few
minutes ago. I couldn't find a looking glass for AS4761 or AS4651. But I
also couldn't hit the websites for either AS, either.

Subject: BGPMON Alert Questions
So I setup BGPMON for my prefixes and got an alert about someone in
Thailand announcing my prefix. Everything looks fine to me and I've
checked a bunch of different Looking Glasses and everything announcing
correctly.
I am assuming I should be contacting the provider about their
misconfiguration and announcing my prefixes and get them to fix it. Any
other recommendations?
Is there a way I can verify what they are announcing just to make sure they
are still doing it?
Here is the alert for reference:
